CRON jobs are Scheduled Tasks on Windows, indeed.
We really don't have any tutorials, except a video tutorial. That one only talks about CRON jobs on cPanel hosts which is what the overwhelming majority of people in need of a video tutorial use.
The documentation is universal, for Linux, macOS, and Windows. I know because I wrote it, using all three OS to make sure the instructions make sense.
Using Windows' Task Scheduler is fairly trivial.
Create a Basic Task.
Choose a trigger, e.g. Daily.
For Action you should use Start a program.
In the Program/script you need to select your PHP executable, e.g. C:\PHP\8.3\php.exe
. The exact path will obviously be different, as it depends on where you've installed PHP. Please make sure that you are using the php.exe binary (that's the PHP CLI binary), NOT the php-cgi.exe.
As for the arguments, please check our documentation or, better yet, the Schedule Automatic Backups page of the interface. It will be something like D:\Sites\foobar\cli\joomla.php akeeba:backup:take --profile=2
. Basically everything that follows after the path to PHP in the documentation and our user interface.
Do note that Windows' Task Scheduler is very often a weirdo. The next backup may not be on the same day you set the scheduled task, but one day later. I have no idea why it does that. It's driving me crazy every time I need to test anything on Windows.
As to how to do this for multiple sites, the answer is that you create a scheduled task per site and scheduled backup. Yes, it's annoying, like everything systems management on Windows.
Note: our support will be closed until August 19th.
